To tZZ wiz/0711,` tml/ty con/cern:

Be it known-,that I, CHARLRs E. GERVAIS, acitizen of the United States, residingin New York, borough of Manhattan, in the State of- New York, have invented certain new and.

useful Improvements in Lamps, of which the following is a specification.

In United AStates Letters Patent No. 678,655, granted to me July 16, 19011 have described Io a lamp having two wicks, means for` lighting one of said wicks by aresistance coil or wire, and an extinguishing device for said wick connected with means controlling the electric current for said resistance-coil, so that the I5 current is discontinued and the flame extinguished by the extinguishing device simultaneously or approximately so. The` lamp re. ferred to has two wicks,the second wick beoom` ing ignited from thelame ofthe first after 2o the first has been ignited by the resistancecoil. The flame from the second Wick remains lighted after the extinguishment of the lirst Wick until blown out or extinguished by other means. This lamp when used as a cigar- 2 5 lighter, for which it is in many respects adapted, was found to have some objections. Frequently the user while holding his cigar with one hand would with the other hand retain the extinguishing device for the rst wick in 3o raised position and press the cigar closely to both wicks, thereby displacing the resistancecoil from its proper position for lighting the primary wick or to such an extent removed :from the wick as to prevent it lighting the same at all or even breaking the coil. The coil and wick also by this operationV became covered with cigar-ash, which interfered with the reliable lighting of the wick in sn bsequent use of the lamp.

4o The object of this invention is to provide means for overcoming these evils, so as to render the lamp reliable in operation when used as acigar-lighter. For this purpose the invention consists in the combination, with a lamp-.body,of a head applied to the same and provided with a shoulder at its upper portion, `a hollow guard-cap fitting at its lower end on said shoulder and extending upwardly from the head and provided with openings in ,its 5o side wall and an opening at the top, a Wicktube extending from said lamp-body through thehead and terminating in the upper part of the guard-cap near the top opening' of the same, awick in saidtube and extending from the upper end of the same within the guardeap,'a resistance-wire within the guard-cap adjacent the upper end of said Wick for lighting the same, a swinging arm, and an extinguishing-cap carried by said arm and adapted to close said upper opening in the top of the guard-cap.

-Theobject is, further, to provide means for cutting olf the cigar-ti p simultaneously with the raising of the cap from the guard-cap and with the igniting of the wick, so that the cigar is `prepared for lighting at the same time and by the same operation that the flame is produced. This I accomplishby providing the head of the battery-receptacle, to which the swinging arm is attached, with a curved 7o seat adapted to receive the cigar,and providing the rear portion of the arm with a knife-edge, so that when the arm is operated by a rod, to which one element of the battery is attached for being plunged into the battery fluid, the knife-edge descends to the seat and cuts oi the cigar-tip.

The invention consists, further, in. certain other combinations of parts, which will be fully described hereinafter and finally point- 8o ed out inthe claims.

In the accompanying drawings, Figure 1 is a side elevation; Fig. 2, a vertical central section on line 2 2, Fig. 3; and Fig. 3, atop view of a lamp embodying my invention. S5 p Similar lettersof reference indicate corresponding parts.

Referring to the drawings, A indicates a lamp-body, and B the head of the lamp, which is secured to the body A bya screw-threaded 9o lower portion or'neck ct or any other suitable means. The upper portion of said head is provided with a shoulder d', and on said shoulder is frictionallysecureda guard-cap C, of metal or other suitable material, which extends upwardly from the head and which is provided with openings a2 in its side wall and an opening a3 in its top. Through the headextends a Wick-tube b, which terminates inthe upper part ol the guard-cap adjacent 1o@ the top opening d3. The wick-tube extends vertically, and for protecting the wick against cigar-ash the upper end of thetube is preferably hood ed over by a suitable guard b'. Also the tube is not located directly in the center of the head and guard-cap, butat one side of the same, in such position that the flame as directed by said guard b will pass out of the opening a3 approximately at the center of the same and burn steadily. A wick a4 extends from the lam p-body through thel wick-tube, and a resistance coil or wire b2, of platinum orother suitable material, is arranged in contact with or adjacent the upper exposed end of the wick. Said coil is supported on the one hand by a post b3, of suitable conducting material, rising-from the head, andon the other hand by a post b4, which may be a continuation of a conducting-wire b5, insulated from the head.

1 The head B is provided with a tubularlateral extension c, which engages an extension c/ of the head D oi a suitable receptacle E ot non-conducting material, upon which the entire lamp v'is supported,land which receptacleE forms thejar for an electric battery by which 'current is generated Afor the resistance-coil b2. The receptacle E is supported on a suitable base E of anyv desired form.

Between suitable upwardly-projecting lugs d of the head D is pivoled a' swinging armd', provided at its outer end with a cap d2 of such size as to close the upper opening a3 of the guard-cap C. The head D is attached to a suitable screw-cap D.fadapted to screw upon the jar or receptacle E, and said head is provided with a recess in which is located the head e2 of a bolt e., which is insulated by a suitable` washer e from the head. The bolt passes through the head andcap and a plug e3, said plug being located below the cap and insulated from the same by an insulating-Washer e4. The bolt thereby secures the plug, head, and cap securely together. The head c2 oi the bolt is provided with a bore adapted to receive the end of the insulated conductingwire b5, and a set-screw e5 screws into the head and secures said wire thereto.4 To the plug .c3 are attached by any suitable means two carbon-plates, of which one only, f, is shown in the drawings, said plates being arranged parallel with c ach other. Between the carbon plates, which form the negative elements of the battery, is located a smaller platetof zinc f', forming the positive elementotl the battery and separated from the carbon velements by a pin f 2 of.insulating material, this construction being substantially the same as indicated in my previous patent referred to. The zinc plateis attached to and supported by a rodfs, which is spring-actuated in upward direction, so as to lift the platef" out of the battery fiuid by a suitable coil-spring f4, located in a tube g, insulated by a layer of suitable insulating material from the plug, the making and breaking of the. current being controlled by said rod and connected parts. The rod f3 isyend with a knob 72.

der a.

guided by a plug g2 at the lower end of the between said plug and washer. Y `The rod f3 passes in upward direction through the cap D' and head D and is provided at its upper wardly from its pivot m in the lugs d, and said rear portion d4 is curved and extends adjacent the rod f3 and knob h, so that upon depressing the rod f3 the knob h engages said rear portion d4, and thereby operates the arm d', raising the extinguishing-cap d? from the guard-capi). The head Dis provided between the pivot m and rod f3 with a seat m', preferably curved, as indicated in Figs. l and 3, so as to receive the end of ka cigar. The rearv portion d* oi the arm dis made sharp at its lower side opposite said seat, so as to form a knife-edge m2, adapted to Icoperate with the seat for cutting ed the cigar-tip. The

circuit. of the battery is `from the zinc f', through the rodf, head D, .extension c of thev lamp-head, head B, post b3, resistance-wire b2,

ost b4, wire b5, bolt e', lug e3, and carbon f, P P

and the battery iuid F.

When it is desired to light a cigar, the cigar is placed with its tip on the seat m', as indicated in dotted lines in the figures, and the rod f3 is pushed in downward direction by means of the knob h, thereby cutting od the .tip of the cigar and plunging the Vzinc into the battery iiuid. The current is generated by the battery in the receptacle E and iiows throughthe coursev stated, thereby heating the resistance-coilsuiciently to ignite the wick, the fiame from the same passing through the opening a3, as indicated. The user may now light his cigar by inserting the same in this flame, meanwhile retaining the rod in depressed position. cap C vit is impossible for the cigar to be brought into contact with the resistance-coil,

and all displacement-of the same or covering with cigar-ash is avoided. The guard bf pressed as before, whereby the cap (Z2 is again` raised and the wick again ignited.

The lamp-body A may be filled with cotton or other suitable absorbent substance n, saturated with a combustible duid, or may be illed with the combustible fluid itself.

It is found that after use for some time there may be an accumulation of ashesin the guardcap C, and'for the purpose-of convenientlytremoving these or for inspecting or repairing the parts or trimming the wick when necessary the cap C is made removable, the same being The arm d extends rear-y IOO Ouaccount of the guard- IIO merely frictionally retained upon the shoulv For facilitating removal and replacebedepressed. The cap C is removed by simply4 first Swingin(r the arm clin u ward or backb D p ward direction, as indicated in dotted lines in Fig. l. This operationis permitted by reason of the fact that the rear portion d"1t of the arm is freely movable downwardly at the side of the rod and is not connected directly with said rod. When the arm d' is in this position, the guard-cap C is readily removed, the necessary cleaning,r or repairs made, the cap then replaced, and the arm and cap d2 allowed to descend into normal position. tion was not possible with the extinguishing mechanism shown in my previous patent referred to, as the same was connected with the' battery-rod and was not movable independ-` ently of the same.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- l. Inalamp,thecombinatiomwiththelamp` body, of a head applied to the same and provided at its upper portion with a shoulder,a hollow guard-cap fitting at its lower end on saidshoulder and extending upwardly from said head "and provided with openings in its side walls and an opening at the top, a wick? body, of a head applied to the same and pro` vided at its upper portion with a shoulder, a hollow guard-cap tting at its lower end on said shoulder and extendingupwardly from said head and provided with'openings in its side wall and an opening'at the top, a vertical wick-tube extending from said lamp-body through the head at one side ofthe center of the saine and provided at'its upper end, near the top opening, with an overhanging guard,
